Background and objectives: DNA hyper-methylation is an important aspect involved in carcinogenesis cancer progression, which affects mainly CpG islands of causes inactivation tumour suppressor genes. Therefore hypermethylation status the genomic both transformed cancerous cell lines carcinogen-induced lung was ascertained by analysis expressions certain major specific The other objective to exa...

Mycobacterium avium subsp. paratuberculosis (MAP) is the etiologic agent of Johne's disease in ruminants and there has been a shift in the public health approach to MAP and human diseases like Crohn's disease. The prevention of infection by MAP in ruminants is thought to deter the high impact of economic losses in the level of dairy industry and possible spreading of this pathogen in dairy prod...

Inorganic arsenicals are worldwide environmental contaminants that affect molecular characteristics in biological systems and lead to genomic and epigenomic instability as well as epithelial mesenchymal transition (EMT). In this study, we aimed to investigate whether low levels of sodium arsenite (iAsIII) can influence EMT and genomic instability through microsatellite analysis. We have also de...

objective(s): stem cell differentiation into different cell lineages depends upon several factors, cell cycle control elements and intracellular signaling elements, including p15ink4b and p16ink4a genes. epigenetics may be regarded as a control mechanism which is affected by these factors with respect to their promoter structure.   materials and methods: the cd34 + cord blood stem cells were pu...

In mammals, most new mutations occur in males. But a study of the evolution of a human X to Y chromosomal translocation has revealed a sex bias much lower than previous estimates. Patterns of substitution suggest that differential methylation between male and female germ lines is a key determinant of the mutation rate.

Epigenetic changes of DNA, including methylation, have long been recognized as key indicators various diseases, aging, cancer, and neurological disorders. Biomarker discoveries based on distinct methylation patterns for both hypermethylation hypomethylation lead the way in discovery novel diagnosis treatment targets. Many different approaches are present to detect level whole genome (whole bisu...

Background: Promoter hyper-methylation of tumor suppressor genes is a common event that occurs in cancer. As methylation is a reversible modification, agents capable of reversing an abnormal methylation status should help to combat cancer. 5-Aza-CdR is a DNA methyl-transferase inhibitor. The present study aimed to evaluate the effect of 5-Aza-CdR on the proliferation of human pancreatic cancer ...

Background: Acute lymphoblastic leukemia (ALL) is the most prevalent hematologic malignancy among children. DNA methylation is well known to play a role in the initiation and progression of cancer. This research aimed to characterize the epigenetic inactivation and gene expression of Protocadherin-10 (PCDH10) and Reprimo (RPRM) in pediatric acute lymphoblastic leukemia, which is associated with...
